Finally, what if you have a chromatogram of an amine (polar) and an ether (fairly non-polar). Would the amine have a higher R than the ether if a polar mobile phase like ethanol->methanol was used as the developing solvent? (Answer Yes). !!
Electronic Effects
The effect of electrons that are located in the chemical bonds within the atoms of the molecule is termed an electronic effect. The electronic effect is also explained as the effect through which the reactivity of the compound in one portion is controlled by the electron repulsion or attraction producing in another portion of the molecule.
Drawing Resonance Forms
In organic chemistry, resonance may be a mental exercise that illustrates the delocalization of electrons inside molecules within the valence bond theory of octet bonding. It entails creating several Lewis structures that, when combined, reflect the molecule's entire electronic structure. One Lewis diagram cannot explain the bonding (lone pair, double bond, octet) elaborately. A hybrid describes a combination of possible resonance structures that represents the entire delocalization of electrons within the molecule.
Using Molecular Structure To Predict Equilibrium
Equilibrium does not always imply an equal presence of reactants and products. This signifies that the reaction reaches a point when reactant and product quantities remain constant as the rate of forward and backward reaction is the same. Molecular structures of various compounds can help in predicting equilibrium.
Can you explain more why the answer would be "yes"?
As we know, Like dissolves like that means polar compound are soluble in polar solvent while nonpolar compound is soluble in non-polar solvent.
And Rf value is also depends on solubility of substance in mobile phase, higher the substance soluble in mobile phase higher the Rf.
